<P><STRONG>Function</STRONG>
<P>
Presents a message to the user.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
void DXMessage(char *message, ...)<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>
The message string should not contain newline characters, because the
<TT><STRONG>DXMessage</STRONG></TT> routine formats the message in a
manner appropriate to the output medium.
For terminal output, this includes prefixing the message with the
processor identifier and appending a newline.
The <TT><STRONG>message</STRONG></TT> may be a <TT><STRONG>printf</STRONG></TT>
form string, in which case additional arguments may be
necessary.
<P>
You can also invoke standard error messages by specifying
<TT><STRONG>message</STRONG></TT> as
<PRE>
&quot;#number&quot;
</PRE>
where <TT>number</TT> identifies a message in the file
<TT>/usr/local/dx/messages</TT>.
Note that many of the messages require one or more arguments.
<P><B>Note: </B>In combination with two other library routines,
<TT><STRONG>DXMessage</STRONG></TT> can be used to form
"long" messages.
For details, see <A HREF="progu110.htm#HDRDXBLM">DXBeginLongMessage,
DXEndLongMessage</A>.
<P><STRONG>Return Value</STRONG>
<P>
None.
